** Assigning a calculated value to a resistor in
MATLAB/Simulink**
I have been trying to allocate the calculated varying electrode
resistance value from the Mask block to resistor R, when I try to
create a variable to assign the value on I get the error message
"Unrecognized function or variable". Is there a way I can use to
assign the calculated resistance output to be the value
of resistor R? Please help.
Many thanks,
